Find the average specific heat of the liquid in this temperature range. Assume that negligible heat is transferred to the container that holds the liquid and that no heat is lost to the surroundings. Express your answer in joules per kilogram per kelvin. C = J/(kg - K) Submit Request Answer Part B Suppose that in this experiment heat transfer from the liquid to the container or its surroundings cannot be ignored. Is the result calculated in part (a) an overestimate or an underestimate of the average s O underestimate O overestimate

QUESTION 6 A piece of unknown material weighs 0.4 kg. It is heated to 70 °C, then transferred into a 2 kg bath of oil at 20 °C. The bath temperature eventually reaches 40 °C. Assuming that Cmaterial = 0.6 kJ/(kg-K), calculate the heat in kJ that it lost when placed in contact with the oil. In this case, consider the amount of heat lost to be a positive quantity. Do not include units in your answer and write the numerical value in normal form. QUESTION 7 This problem is concerned with the same situation as the previous problem. A piece of unknown material weighs 0.4 kg. It is heated to 70 °C, then transferred into a 2 kg bath of oil at 20 °C. The bath temperature eventually reaches 40 °C. Assuming that Cmaterial = 0.6 kJ/(kg-K), calculate the heat energy in kJ gained by the oil. Do not include units in your answer and write the numerical value in normal form.

the correct number of significant digits.     1. Look up the density of water at 5.0ºC, 20.0ºC, 22.0ºC, 25.0ºC, and 30.0ºC. Does temperature affect density?     Is temperature a significant source of error for our experiment? Explain
